Application filed July 18,

To all whom it may concern:

Be it known that 1, WILLIAM C. Aorrrnn- KIRGII, a citizen of the United States residing at Ogilvie, in the county of hanabec and State of Minnesota, have invented certain new and useful Improvements in Bulletin or Notice Boards of which the following is a specification, reference being" had to the accompanying drawings.

This invention relates to display devices, and particularly to aboard for supporting notices or bulletins.

The general object of the invention, is to provide a bulletin supporting board and in connection therewith means whereby bulletins may be held to the board, without the use of tacks, paste, or other like attaching means.

A further object is to provide a bulletin board constructed of sheet metal so designed that the bulletin board may be pressed out of the sheet metal and in this connection to provide a bulletin board having a hood which will extend over the notices or bulletins on the board.

A further object is to provide a construction which is very light and yet strong, and in which the bulletins or notioesshall be firmly locked to the board.

Other objects will appear in the course of the following description. I

My invention is illustrated in the accompanying drawings, wherein Figure 1 is a perspective lview of a bulletin board constructed in accordance with my invention; 1 r

Fig- 2 is a section onthe line 2-2 of Fig. 1; i

Fig. 3 is a fragmentarylsection on the line 3-3 of Fig. l;

l Fig. Al is a rragmentary seetion on the line H of Fig. 1; and

Fig. 5 is a fragmentary transverse section on the line 5-5 of Fig. 1. I

Referring to these drawings, 10 designates the bulletin board pr0per,- whichis made of sheet metal and is preferably made of sheet metal of about No. 2.0 gage. The sheet metal is first cut to the proper shape and then stamped or soldered or welded at 1 the joints. As illustrated the board is recfangular in form and formed to. provide a hood l1 projecting upward and'outward to any desired degree, the metal of the board being stamped outward at the sides to form.

self and then rearward as at 14 to form a;

flange disposed-above the lower end of the board and at the top of the board there is a like flange 15.

The end walls or flanges 12 at their upper forwardly enlarged ends are formed with sockets 16 which are pressed out of the sheet metal and disposed in these sockets is the transversely extending rod 17 ,which is disposed adjacent the face of the board and well beneath the hood 11. v

The face of the board 10 is formed with a plurality of vertically extending grooves 18, these grooves being pressed out oi the sheet metal and extending nearly the entire length of the board. lldounted upon the rod 17 are a plurality of clamps 19. These clamps are slightly curved for their entire length and a f-shaped rio 20. This V-shaped rib is At its lower end the notched at intervals as at 21 so that the V- loosely embraces the .rod 17 so that the clamping members may he slid along the and for a purpose which will be later stated. At their lower ends, each clamping member isenlarged and rotatably mounted in'this enlargement is a stud 23 having at its outer end a knob 24 whereby the stud may be rotated and having at its inner end a radially projecting lug 25 adapted to engage behind the lower margin of the sheet metal bulletin board. It will be seen that when so engaged the resilience of the clamping members 19 will urge the clamping members outward so that the lug 25 will trictionally engage with the bulletin board so that the stud 25 cannot be accidentally ro tated. A; slight depression may be made in the margin of the board with which the lug 25 could engage to prevent the accidental rotation of the stud.

There may beany number of grooves 18 on the faceof the bulletin board. 1 have shown three grooves adjacent the outer mar ins of the board and two pairs of groovesa jacent the middle of the board, but I do n0t -WiSh to be limited to this. By providing a plurality of these grooves and mounting the clamping members for longitudinal movement along the rods, it is; obvious that bulletins of various size maybe readily clamped in position upon the board, and it will also be seen that when these bulletins are in place upon the board and engaged by the clamping members, the lateral margins of the members will be "forced into the grooves and be interlocked with the bulletin board by the clampin? members and the grooves.

or the purpose of mounting the bulletin board upon a standard 26, which standard 1 have illustrated as a metallic column, 1 provide the clamps 2 7 which are bolted or riveted to the flanges l4 and 15-; I do not wish to limit myself to this ,means for supporting the bulletin board, however, as other means may be used. Where ,large bulletin boards are used, it is obvious that a plurality of columns may be used for supporting the board. It will also beobvi,ous that my bulletin board ma be modified in manyways without depart ng from the spirit of the invention. I

Having thus described my invention, what I claim is L" 1. A bulletin board Having vertically extending grooves in its face, clam ing members pivotally mounted upon the card and adjustable transversely thereof and termed to engage in said grooves, and means for locking the clamping'members in clamping position.

2. Abulletin board having a series of vertically extending grooves across its face, a rod extending transversely of the board, clamping members pivotally mounted upon the rod and adapted to engage in said grooves, and means carried on the clam ing' members and engageab e with the boar for holding the clamp ing members against the face of the board and in clampingposition. A bulletin board having a plurality of vertically disposed grooves in its face, a plurality oi pivoted clamping members each having a V-shaped rib on its inner face adapted to engagd in the groove, the clamping members being mounted upon the board for movement transl ersely thereof and piv-- otal movement in a plane at right angles to the face of the board, and means for holding said clamping members in clamping posi- 1 tion.

t. A bulletin board having a plurality of vertically disposed grooves in its face, a plurality of pivoted clamping members each having a V-sl1apedr=rib on its inner face adapted to engage in the groove, the clamping members being mounted upon the board for movement transversely thereof and pivotal movement in a plane right angles to the face of the board, and means "for holding said clamping members in clamping posibeing resilient curved toward tion, said clamping members and longitudinally convexly the face of the board.

5. A bulletin board made of sheet metal formed to provide a hood and outwardly projecting side flanges, a rod mounted beneath the hood and'extendin transversely across the board and supports by said side flanges, the face of the board being formed with a plurality of stamped vertically disposed grooves, clamping members having heads at their upper ends pivotally and slidingly engaging said rod, the clamping members being curved outward and downward, the lower ends of the clamping members hav ing means for engaging the lower margin of the board to hold them in clamping position against the face of the board.

6. A bulletin board made'of sheet metal formed to provide a hood and outwardly projecting side flanges, a rod mounted beneath the hood'and extending transversely across the board and supported by said side flanges, the face of the board being formed with a plurality-of stamped vertically disosed grooves, clamping members having heads at their upper ends pivotally and slidingly engaging said rod, the clamping members being curved outward and downward, the lower ends of the clamping members having means for engaging the ower margin of the board to hold them in clamping position against the face of the board, said means comprising a rotatable stud having a knob at one end and a lug 'on the inner end engaging behind the lower margin of the board.

7. A bulletin board formed of sheet metal and shaped to providea forwardly projecting hood at the upper edge of the board and a rearwardly projecting flange and a rearwardly pro ecting flange at the lower end of the board, the sides of the bulletin board being outwardly bent and then rebent to extend rearward to form outwardly directed side flanges, a rod supported in the upper ends-of said side flanges beneath the hood, and clamping members each rotatably mounted at its upper end upon the rod and slidably engaged therewith, said members being resilient and outwardly and downwardly curved, and means on the lower edge of said members for engaging the lower margin of the bulletin board to hold the.

flanges beneath the hood,-

aaeaeao and clamping members each rotatably mounted at its upper end upon the rod and slidably engaged therewith, said members bein resilient; and outwardly and downwar ly curved and means on the lower edge of said members for engaging the lower margin of the bulletin board to hold the clamping members in clamping position, and column clamping devices mounted upon the upper and lower flanges of thebulletin board.

9. A bulletin board formed of sheet metal and shaped to provide a forwardly projecting hood at the upper edge of the board and a rearwardly projecting flange and a rearwardly projecting flange at the lower end of the board, the sides of the bulletin board being outwardly bent and then rebent to extend rearward to form outwardly directed side flanges, a rod supported in the upper ends of said side flanges beneath the hood, and clamping members each rotatably mounted at its uppen end upon the rod and slidably engaged therewith said members being resilient and outwardly and downwardly curved, and means on the lower edge of said members for engaging the lower margin of the bulletin board to hold the clamping members in clamping position, the sheet metal bulletin board being formed with a plurality of vertically extending V- shaped grooves, and each clamping member on its inner face being formed with a V- shaped rib engageable in the groove, the ribs being notched at intervals to permit the clamping member to normally curve outward and downward.
